The sad thing is there is NO standard for these bullets (and for any other 'aggressive' secant designs). Traditionally, VLDs were seated into the lands, but a significant minority of barrels and/or chambers don't like them there. To Berger Bullets' surprise many years back, experimenters found that large jumps worked well in some (many?) rifles, hence the company's longstanding advice on 'tuning' VLDs testing as far out as 120 thou' jump.

Berger has pretty obviously felt nervous about the VLD design's reputation and its various issues, hence the 'Hybrid' design being adopted as a third plank to its product range to retain the VLD's low drag performance, but make it easier to 'tune'. The Hybrid is now the dominant match shooting type in its product range and once popular older 'BT' (tangent ogive) match designs (eg 90gn 224; 210gn 0.308) are being gradually and quietly withdrawn. I suspect that if thin-jacket VLDs hadn't turned out to perform so well as hunting bullets, the company would also have largely dropped the VLD from its range.
10 out of 10 for Berger's naming policy clarity on match types: BT; LRBT (tangent ogive longer neck section) VLD; Hybrid; LR Hybrid; OTM Tactical. You know exactly what you're buying in design terms. By contrast, Hornady and Sierra have introduced new models under 'generic' product names that are radically different design types from other range members or older models. Sierra's MatchKing range varies from antediluvian short-nose tangent models with 7-calibres radius nose sections and a perfect tangent ogive form to newer models like the 183gn 0.284" SMK with 28-cal radius front ends and
really aggressive nose to shank junctions that are uber-finicky to tune. The plastic tipped TMK lines vary considerably model to model in their shapes, some as out and out tangent models, some full-blown VLDs and whilst all Hornady ELDs are secant nose designs, they also vary considerably in this respect making some harder to tune than others.
AFAIK, there is only one real source of information on this: Bryan Litz / Applied Ballistics LLC's
Ballistic Performance of Rifle Bullets now in its third edition (and lacking several models still such has been the frenetic pace of new introductions in recent years, so a 4th edition must be coming soon - hopefully!).
